Abstract: 1,037,284. Semi-conductor devices. ASSOCIATED SEMICONDUCTOR MANUFACTURERS Ltd. Nov. 27, 1964 [Nov. 27, 1963], No. 46892/63. Heading H1K. A semi-conductor crystal body is immersed in a solution containing an oxidizing agent and a doping substance to form an oxide layer containing doping substance over at least part of the surface of the body, and is subsequently heated. The process may be used to diffuse the doping substance into the semi-conductor body or to prevent surface depletion effects caused by diffusion of impurity out of the body. In a first example a P-type silicon body was lapped and etched, and then masked using a photo-resist. Any oxide layer was removed by etching and the body was then immersed in a boiling solution of concentrated nitric and phosphoric acids to form a doped oxide layer. The body was then ultrasonically washed and then heated to diffuse the phosphorus into the body. Leads were attached to form diodes. In a second example diodes were prepared as in the first example except that wafers of N-type silicon were used and the phosphoric acid was replaced with boric acid. In a third example a planar diode was manufactured by treating a high resistivity P-type silicon wafer with the solution used in the second example and then heating the body and diffusing-in an N-type deposit, the boron diffusing into the surface from the oxide layer preventing the formation of an inversion layer. In a fourth example aluminium, gallium, indium, thallium, arsenic, antimony and bismuth were each diffused into a silicon wafer of appropriate conductivity type using an oxidizing solution of nitric acid saturated with aluminium sulphate, potassium gallate, indium nitrate, thallous nitrate, sodium arsenate, potassium antimony tartrate, and bismuth nitrate respectively.

The preferred ketone is methyl isobutyl ketone and the preferred hydroxide is sodium hydroxide. The process is preferably effected in the absence of water but some water may be present especially if it is first desired to obtain a monoaryl N,N- dialkyl phosphoramidic monochloride intermediate which is then reacted with a different phenol to form a mixed diaryl ester amide product. The product is recovered by separating off the inorganic halide formed, e.g. by water washing or centrifugation, and then distilling off the ketone which may be recycled for further use. The products are useful as flame retardants for a variety of natural and synthetic polymeric products. Dimethyl phosphoramidic dichloride is prepared by reacting 38À5 mole of POCl 3  with 11À2 mole of dimethylamine.

Abstract: 1373631 Shearing; Fixing nuts in sheets MACLEAN-FOGG LOCK NUT CO 14 Oct 1971 [23 Oct 1970] 47877/71 Headings B3W and B3H Apparatus for feeding clinch nuts to a workpiece, the clinch nuts being in the form of a strip comprising a plurality of aligned nuts 20, Fig. 6, secured together by relatively thin connecting means 33, 34, holding adjacent nuts in spaced relation to one another, the apparatus comprising a plunger 31, Fig. 10, reciprocable in a first opening in a housing, a second opening in the housing shaped to receive the strip and intersecting the first opening, means 65 for intermittently advancing the strip through the second opening towards the first opening, shear means operated by the plunger to shear a nut from the strip and move the sheared nut through the first opening, and means mechanically connected to the plunger for intermittently advancing the strip through the second opening in timed relation to the movement of the plunger. With the apparatus in the position shown in Fig. 10, the strip of nuts 43 is advanced by an operator into contact with surface 87 of drive link 73 and the workpiece 21 is located under punch 31. The punch 31 is then lowered by a ram against the resistance of spring 54 and causes roller 76, mounted on the drive link 73, to ride along cam surface 79, Fig. 51. The drive link thus moves to the left as seen in Figs. 10 and 15, and through rocker arm 66, imparts this movement, at an amplified rate to part 65. The pawl drops into an opening 37, Fig. 6, between adjacent nuts in the strip 43 and advances the strip into the apparatus. As roller 76 leaves cam surface 79 and moves on to vertical surface 83 of the punch 31, forward movement of the strip ceases. Continued downward movement of the punch shears the end nut from the strip at the mid point of connecting flanges 33, 34 and pushes the severed nut through the workpiece 21. The nut and workpiece are then clinched together by the punch 31 and die 25. On return movement of the punch, a pin 81 mounted on drive link 73 moves along cam surface 80 of the punch, thus moving drive link 73 to the right, as seen in Fig. 15, taking pawl 65 with it through the operation or rocker arm 66. The strip nuts are held against backward movement by a finger spring 59.
